Tiny drones are a dime a dozen now, but back in early 2015, they were somewhat of a novelty. UK-based Torquing Group set up a Kickstarter for their smartphone-controlled drone called ZANO in January of that year. Something like a palm-sized drone with the ability to take selfies and HD video shouldn't have a problem raising funds, and it didn't. In fact, it was a Kickstarter darling — the self-proclaimed "most sophisticated nano drone in the world" exceeded its goal of £125,000 ($190,000) and managed to raise over £2 million (almost $2.5 million).
The folks over at Torquing Group promised they would be shipping out drones to backers six months later. Just like our favorite space-aged laser razor, ZANO didn't deliver what they promised, and people started to get suspicious when they got zilch. ZANO was still in the prototype stage when they should have been shipping out drones — also, according to Slate, Torquing Group was up to their eyeballs in debt and used some of the money for dubious purposes, like buying BMWs for high-profile investors.
Torquing Group ended up going bankrupt, but they did manage to send a handful of ZANOs out to backers in November, 2015. The verdict: dollar-store balsa wood planes could fly better than the ZANO, and those lucky enough to actually get one were extremely disappointed.
